Notable points were: l) Regular occurrence of Brown-winged and Crested 
Terns; 2) High proportion of white-phase Red-footed Boobies (ca. 1 / 2 ); 
3) Absence of Blue-faced Booby; 4) Low occurrence of Sooty Tern; 5) Good 
numbers of White Terns (a different form than the Phoenix/Line populations) 
6) Presence of Tahiti Petrel. 
White-capped Noddy and Red-footed Booby appear to be ecological re¬ 
placements for Sooty Tern and Blue-faced Booby. The apparent absence of 
Blue-faced Booby may in fact be a causative factor that led to the high 
• proportion of white-phase Red-foots. A number of unidentified Procellarids 
were chased by the skiff but none could be approached readily. These were 
almost all, I believe, Tahiti Petrels. About a dozen such birds were seen 
from the skiff but none were observed from the ship.
